In 1920, Western Union has implemented the world's first transmission of images over the ocean. Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. In 1877, starting from September, New York City residents began to have the opportunity to check the time on clock with the "time ball", located on the roof of constructed in the same year a new corporate headquarters - Western Union Building. The size of the commission fee for the transfer is charged according to the Western Union tariffs and depends on the amount of money sent. In 2000 was launched the Web site westernunion.com, with which users from certain countries can independently transfer funds online.
